DRAFT/working in progress

- Routine to download data: using ACS-5Y-2016 for all Texas. [script]
- Define variables: SVI variables
- Save the variables definition
- Define geography: tracts and block-groups (BGs) and download estimates and margin-of-error (MOE)
- SVI variables for all Texas tracts -- melted variables (SHP zipped)
- SVI variables for all Texas tracts -- melted variables (big list)
- SVI variables for all Texas BGs -- melted variables (big list)
- Cast data:
- SVI variables by TRACT -- Estimates (all, include missings), tabulated values
- SVI variables by TRACT -- MOE, tabulated values
- SVI variables by BG -- Estimates (all, include missings), tabulated values
- SVI variables by BG -- MOE, tabulated values
- Remove tracts/BGs with zero population: 38 tracts out of 5265 (Texas)

or, Remove tracts/BGs with zero for all variables: 36 tracts out of 5265 (Texas) [did this one!] - SVI variables by TRACT -- Estimates (cleaned), tabulated values
- SVI variables by BG -- Estimates (cleaned), tabulated values
- Summary of varibles:
- A simple to use summary of the variables (estimates, all) by TRACT
- A simple to use summary of the variables (MOE) by TRACT
- A simple to use summary of the variables (estimates, all) by BG
- A simple to use summary of the variables (MOE) by BG
- Define the standardize formula: $$z_i = {{x_i - \mu_x} \over \sigma_x}.$$
- Stantardize estimates:
- SVI variables by TRACT -- Estimates (cleaned and standardized)
- SVI variables by BG -- Estimates (cleaned and standardized)
